METALLOGRAPHIC RESEARCHES ON WELDED CONSTRUCTION OF THE TELECOMMUNICATION ANTENNAE

Modern telecommunications antennas are made in welded steel pipes. Constructive complexity, functiona l, parametric and resistance require special materials and a blend of modern technology. The paper presents a welded construction made of telecom antennas welded pipes using welding manual process and "very short arc sp ray" process. Two welding processes of metallographic samples taken are presented: welding with a metal coated elect rodes made by MAG and by "very short arc spray". The structures were compared using microscopic examination, resulti ng in the conclusion of the joining process.
